Clinton Correctional tailor Joyce Mitchell has had some explaining to do ever since turning herself in for helping convicted murderers Richard Matt and David Sweat with their escape plans. On Tuesday, Mitchell pled guilty to delivering contraband to the prisoners and playing a critical role in their flight.

Soon after the month-long manhunt began, Mitchell was charged with smuggling hacksaws and escape tools to the prisoners, while also planning to kill her husband and drive the fugitives to Mexico. A month after backing out of the plan, Mitchell appeared before court and formally acknowledged her collaboration with Sweat and Matt.

Mitchell’s sentencing date was not yet decided, but she could face anywhere between 2 1/2 to 7 years in prison under the terms of her plea deal with prosecutors. Gene Palmer, who was also suspected of assisting the trio, was released on bail, believed by authorities that he was duped by Mitchell as part of her plan.
